Eight air filters in the Central-Wan Chai Bypass tunnel, Hong Kong
The tunnel forms part of the new strategically important road called the Central-Wan Chai Bypass running along the north shore of Hong Kong island. The dual three-lane tunnel is 3.7 km long. The tunnel has two traffic tubes, each with three lanes and runs partly under the water's surface.
In June 2014, FILTRONtec was commissioned by the Government of the Hong Kong Special Administrative Region with the planning, delivery and installation of eight air purification systems to filter the total polluted air escaping from the tunnel with a whole air flow volume of 1500 m³/s.

Air filter system in the M5-East tunnel in Sydney
In 2004, we were commissioned by the Australian Road and Traffic Authority (RTA) to equip the M5-East tunnel in Sydney with an air filter system, after having emerged as one of the winners from a world-wide technical qualification contest.
In addition to the entire air filter system, we also designed, supplied and installed fans, silencers, fire dampers, as well as the required electrical, measuring and control technology. After successful commissioning, the plant was handed over in April 2010.
